HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.

In HD Tach we get to see if a SSD performs steadily across the entire drive. Other than a little blip where cache changes, the OWC Mercury holds a steady line across the graph.

Again we see performance that is straight as an arrow except for the very beginning of the test where the cache changes. The OWC Mercury Extreme Performance SSD runs similar to the other SF-1200 drives we have tested.
